STREET CURB AND SUBSOIL DRAIN.

SPECIFICATION forming part of Letters Patent No. 899,194, dated March 5, 1889.

Application filed NovenrherlZ, 1888. $erial1l 290,633. (No model.)

To a. whom it may concern:

Be it known that I, HENRY S. HALLWOOD, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in a Combined Street- Curb and Subsoil Drain, of which the following; is a specification.

My invention relates to the improvement of sidewall; and street-curbing; and the objects of my invention are to provide a simple and inexpensive street-curb, to so construct the same as to drain the foundation and sub soil of sidewall: and street pavements and to conduct the drainage therethrough to a sewer or other desired point beneath the gutter or curl) of the street, and to form therein a coni duit for the passage of electrical wires, cables,

pipes, the. These objects I accomplish in the manner illustrated in the accompanyiu d rawings, in which- Figure 1 a transverse section of one of my improved curbing-blocks, and Fig. 2 is a perspective view of the same.

Similarlctters refer to similar parts through-- spectively, in opposite sides of the lower portion of each of the l'iloclcsA, said passagesbeing' made to comm unieate, as shown in Fig. 1 of the drawings, with the hollow 1;. Any desired number of said holes (1 a may be formed in said block, and although preferably made to enter the hollow ll at right angles therewith, as shown, may be formed at other angles, as desired. Passages c on the inner side of the curb are, for obvious reasons, preferably formed at a point slightly below the line of holes 0.

(Z represents an upper hole or hollow made to pass longitudinally through the block at a 2 point preferably above the hollow Z). The

outer side face of block A is, adjoining its upper end, usually beveled, as shown, while the upper surface of the block maybe corrugated or smooth, as desired. The method of laying these blocks is similar to that employed in laying the ordinary curbstones, their ends being closely joined in any desirable manner.

It will be readily seen that the hollow b of the block herein shown will, through the passages c and c, afford an outlet for the drainage of the subsoil ol' the sidewalk and the street-pavcmen t [found ation. The hollow b of the curb th us formed may be made to com: municate with a sewer-drop at the street-corners in any manner desired.

In case it is desired, the hollow or hole (I may be utilized as a conduit for pipes of any characte r, or for electrical wire, thus obviating the necessity of forming separate excavations for said pipe, and doing away with the poles usually employed in conducting wires from one point to another.

The character of the material hereinbel'ore mentioned as preferably used in the formation of my improved curbbloeks is such as to be impervious to moisture, the deteriorating effect of which upon wires charged with electricity is well known.

It desired, the herein-shown blocks maybeiiorined in two parts, or may be formed with channels in their outer surface for the reception of piping, or other obstacles which may be met with in laying the curb.

Although the herein-described device is adapted to till both the oltiees of curb and conduit, it is obvious that the expense of formation and construction will not vary much from that incurred in producing the ordinary curb.

In case it is necessary to break the line of curb by the intersection therewith of a street or alley, where no eonn ection. can be made with the sewer, the hollow of the two ends of the curb maybe connected by ordinary sewer or other pipe.

Having now fully described my invention,

what I claim, and desire to secure by Letters Patent, is

l. A street-curb block havi 115; its lower half wider than its upper half and said upper half beveled on one side, and the lower half prosages d and I) being made to communicate by means of openings, substantially as described.

vided with a longitudinal passage, Z), and lat eral openingsleading into the passage b, substantially as and for the purpose specified.

2. A street-curb block having its lower half 5 wider than its upper half, said npperhalf having a longitudinal passage, (1, and the lower half having a longitudinal passage, 7), said pas
